A 25-year-old woman with intractable seizures underwent FDG PET/MRI for seizure focus localization. MRI demonstrated bilateral carpetlike nodular subependymal gray matter and asymmetrical focal dilatation in the right temporal horn. PET/MRI showed increased FDG within subependymal gray matter with significant hypometabolism in right anterior temporal lobe. EEG and ictal semiology confirmed the right temporal seizure origin. This case highlights the importance of identification of gray matter heterotopia on FDG PET/MRI.
一位 25 岁的女性因难治性癫痫接受了 FDG PET/MRI 以定位癫痫灶。MRI 显示双侧脑室内地毯样小结节状室管膜下灰质和右侧颞角不对称性局灶性扩张。PET/MRI 显示室管膜下灰质内 FDG 摄取增加，右侧前颞叶代谢明显降低。EEG 和发作症状学证实了右侧颞叶起源的癫痫。本病例强调了在 FDG PET/MRI 上识别灰质异位的重要性。
